Isolated Heart Perfusion System for Small Rodents Hugo Sachs Elektronik Harvard Apparatus has always provided top-notch, fully integrated physiology research systems. Continuing our tradition of innovation and high performance we are happy to unveil the next generation Isolated Heart Perfusion System for Small Rodent models, the new IH-SR. For nearly two decades the Hugo Sachs Elektronik IH-series of Isolated Heart Systems has been the gold standard for cardiac physiology measurements in both Langendorff and Working Heart perfusion modes. Today, the IH-SR continues to lead the way with an expanded range of measurement capabilities and ease of use which breaks new ground in ex-vivo cardiac research. What makes the IH-SR so Revolutionary? What makes the IH-SR unique is the revolutionary Perspex construction which simply cannot be matched. The use of Perspex instead of traditional glass allows our engineers to mill the perfusion pathway directly into the solid Perspex blocks. The result is what we call a Solid State Physiological Perfusion Circuit (S 2 P 2 C). This patented perfusion technology ensures a precisely repeatable non-turbulent perfusion pathway for the highest fidelity pressure and flow measurement. This combined with the naturally excellent thermal properties of Perspex, creates a system that allows control, maintenance and monitoring of circulatory parameters in a way that is more physiologically relevant than any conventional perfusion system. 2 physiology@harvardapparatus.com www.hugo-sachs.de www.harvardapparatus.com

IH-SR Features & Benefits The Langendorff System The IH-SR always starts as a Langendorff system. This means a configuration solely for retrograde perfusion down the aorta (toward the heart). In this mode, the aortic valve prevents the perfusate from entering the left ventricle, but the coronary arteries are perfused via the coronary ostia which are located just outside the valve. Perfusate drains as effluate from the coronary circulation via the coronary sinus and tends to drip from the apex making it easily available for collection. The IH-SR configured in this way provides an excellent platform for physiological monitoring using the robust Langendorff assay. Perfusions of several hours are typical, allowing a wealth of data to be collected from individual specimens. The Working Heart System The modular nature of the IH-SR allows for initial integration or later upgrade with the Working Heart perfusion pathway. This enables orthograde perfusion: entering the left atrium, flowing through the left ventricle and exiting the aorta. In this way, a more physiological assay of ventricular contractility is possible as the left ventricle is now fully-ejecting and performing pressure-volume and acceleration work. In order to fully exploit this advantage, the IH-SR includes a specialized pathway which easily allows introduction of a Pressure or Pressure-Volume catheter directly into the left ventricle via the aorta. In either configuration, the IH-SR can be outfitted as a complete Cardiac Physiology Workstation with a range of measurement devices, signal conditioning equipment and acquisition & analysis software to provide a superior solution for virtually any study. To get started, select the basic system then add specific options to suit the particular needs of your study. If any questions arise, our expert technical team of scientists and engineers is always ready to assist with system configuration, application support or custom design requests.
